Este análisis se basa en el último set de #datosabiertos disponibles para Perú, generado por lxs colegas de @INS_Peru y compartidos en @GISAID. Llegan hasta la última semana octubre y se suben nuevas secuencias todas las semanas.

Hace unos días les hablé de las múltiples variantes omicrones que han aparecido: Linajes distintos entre sí pero que convergen en las mismas mutaciones de la proteína spike que se asocian a unión de anticuerpos y afinidad por el receptor ACE2.
